Notes about the UBK file extension:
To open this file type, a required software must be installed. Without it you only see a Windows message "The following file cannot be opened
" (Windows 7) or "How do you want to open this file?
" (Windows 10) if you double-click the file. There click on "More apps"
and choose a suitable software to view such files on your PC or from email attachments.
The UBK file type is primarily associated with 'Embiid Reader' by Embiid Inc.. The Embiid Reader for Windows is an application that allows the user to read books and documents using the font face, color, and size as well as the background color of choice. It was designed with the vision-impaired in mind, and is distributed as freeware. UBK is a proprietary file-type for the Embiid Reader. Any Embiid Reader can read any UBK file. The UBK file uses encryption, but is not keyed to a specific Embiid Reader.
